sir. for good fuel economy, I'll recommend ZIC A (10w-40). It would be best choice. Or any other oil company having 10w-40 viscosity.
But if you've already consumed it and willing to change, then use Toyota's Petron 20w-50. Majority of the consumers of this oil says "thumbs up". Specially good pickup and reduces the engine sounds also.
